[0003] In order to avoid mutual interference between the battery cells in the box body and the outside world (including the outside environment and external devices), how to improve the sealing performance of the box body has become a technical problem to be solved. UTILITY MODEL CONTENT

[0004] Therefore, the present application aims to provide a battery pack box and a battery pack to at least partially solve the problem of how to improve the sealing performance of the battery pack box.

[0005] To achieve the above purpose, the present application provides a battery pack box in a first aspect, which comprises: an upper box body and a lower box body connected to each other to jointly form a containing space; the lower box body comprises a bottom plate, and a connecting groove is formed in a wall surface of the bottom plate; the upper box body comprises a top plate and a first side plate, one end of the first side plate is connected to the top plate, and the other end is inserted into the connecting groove; a connecting layer is arranged in the connecting groove, and the first side plate is sealingly connected to at least part of the inner surface of the connecting groove through the connecting layer.

[0006] Optionally, a groove wall of the connecting groove close to the center of the bottom plate is defined as a first groove wall; the first side plate is sealingly connected to the first groove wall through the connecting layer.

[0007] Optionally, a connecting layer is arranged between the first side plate and the groove wall of the connecting groove, and between the first side plate and the groove bottom of the connecting groove.

[0008] Optionally, the connecting groove is arranged on a first bottom plate wall surface of the bottom plate facing the top plate.

[0009] Optionally, the lower box body comprises an end plate connected to the bottom plate and protruding from the first bottom plate wall surface; a side wall of the connecting groove close to the end plate is connected to the side wall of the end plate.

[0010] Optionally, a first sealing member is arranged between the first side plate and the end plate; the connecting groove has a first groove wall, the first groove wall is flush with a part of the side wall of the end plate close to the first bottom plate wall surface, and the thickness of the connecting layer between the first groove wall and the first side plate is the same as the thickness of the first sealing member.

[0011] Optionally, the top plate is connected with two first side plates, the connecting grooves are provided with two and are respectively located at two sides of the end plate, and the first side plates are connected with the connecting grooves one by one.

[0012] Optionally, the connecting layer is a glue solidification layer.

[0030] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0031] It should be noted that the relative arrangement of the components, numerical expressions and values set forth in these embodiments are not intended to limit the scope of the present application unless otherwise specifically stated.

[0032] It should be understood that the sizes of the various parts shown in the drawings are not necessarily drawn to scale for the sake of convenience.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the scope of the application or its application or uses.

[0034] ​It should be noted that, unless otherwise defined, technical terms or scientific terms used in the embodiments of the present application shall have the common meaning understood by one of ordinary skill in the art to which the embodiments of the present application belong. The terms "first", "second", and similar terms used in the embodiments of the present application do not denote any order, quantity, or importance, but are merely used to distinguish different components. The terms "include", "contain", and similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects. The terms "connect" or "connected" and similar terms do not mean physical or mechanical connection, but can include electrical connection, whether direct or indirect. The terms "upper", "lower", "left", "right", and the like merely represent relative positional relationships, which can change when the absolute positions of the described objects change.

[0035] To improve the sealing performance of the box in which the battery cell is placed, in some embodiments, the box includes a box cover and a rectangular lower box, and the upper end of the rectangular lower box is provided with an opening, and the box cover can be closed with the rectangular lower box to block the opening. To improve the sealing performance of the box, a lower sealing flange is arranged around the opening on the upper end of the rectangular lower box, and the lower sealing flange has an annular lower flange surface located on the same horizontal plane. Correspondingly, an upper sealing flange is arranged around the lower end of the box cover, and the upper sealing flange has an annular upper flange surface located on the same horizontal plane. The upper flange surface and the lower flange surface are sealingly connected to each other to form a sealing structure.

[0036] However, the applicant found that the upper flange surface and the lower flange surface are horizontally arranged, and in order to ensure the sealing performance, the length and width dimensions of the upper flange surface and the lower flange surface are relatively large. At the same time, since the upper flange surface and the lower flange surface cannot be arranged with battery cells above and below, this leads to a low volume assembly rate of the battery pack using the box, and a low energy density.

[0037] To solve the above problems, as shown in Figure 1 , Figure 1 A perspective view of a battery pack box is shown, which includes an upper box 100 and a lower box 200 connected to each other to jointly enclose a containing space; the lower box 200 includes a bottom plate 210, and the upper box 100 includes a top plate 110 and a first side plate 120; as shown in Figure 2 , Figure 2 An enlarged view of part A in Figure 1 is shown, the wall surface of the bottom plate 210 is provided with a connecting groove 211, one end of the first side plate 120 is connected with the top plate 110, and the other end is inserted into the connecting groove 211; the connecting groove 211 is provided with a connecting layer 300, and the first side plate 120 is sealingly connected with at least part of the inner surface of the connecting groove 211 through the connecting layer 300.

[0038] For example, the connecting groove 211 can be arranged on the upper wall surface (i.e. the wall surface facing the top plate 110) of the bottom plate 210, and the end of the first side plate 120 away from the top plate 110 can be inserted into the connecting groove 211 along the height direction of the battery pack case (e.g. the Z direction of the X-Y-Z coordinate system shown in FIG. 1) ; or the connecting groove 211 can be arranged on the side wall surface (i.e. the wall surface of the side wall adjacent to the upper wall surface) of the bottom plate 210, and the end of the first side plate 120 can be formed with a bent flange, and the first side plate 120 can be elastically deformed to allow the flange to be inserted into the connecting groove 211 when the upper case 100 and the lower case 200 are assembled. Figure 1 And Figure 2 For example, the connecting groove 211 can be arranged on the upper wall surface (i.e. the wall surface facing the top plate 110) of the bottom plate 210, and the end of the first side plate 120 away from the top plate 110 can be inserted into the connecting groove 211 along the height direction of the battery pack case (e.g. the Z direction of the X-Y-Z coordinate system shown in FIG. 1) ; or the connecting groove 211 can be arranged on the side wall surface (i.e. the wall surface of the side wall adjacent to the upper wall surface) of the bottom plate 210, and the end of the first side plate 120 can be formed with a bent flange, and the first side plate 120 can be elastically deformed to allow the flange to be inserted into the connecting groove 211 when the upper case 100 and the lower case 200 are assembled.

[0039] Optionally, the connecting groove 211 can be milled or punched on the upper wall surface of the bottom plate 210, or the bottom plate 210 can be integrally extruded with the connecting groove 211 directly formed thereon.

[0040] For example, the connecting layer 300 can be a structure layer formed by solid adhesive (e.g. double-sided tape), or a structure layer formed by solidification of fluid adhesive (e.g. glue), or a structure layer formed by welding.

[0041] For example, the first side plate 120 is sealingly connected to the surface of the groove wall or the surface of the groove bottom 2112 of the connecting groove 211 through the connecting layer 300.

[0042] In the embodiment, the inner surface of the connecting groove 211 can include a horizontally arranged (e.g. horizontally arranged) groove bottom 2112 and a vertically arranged (e.g. vertically arranged) groove wall, and the first side plate 120 can be sealingly connected to the groove bottom 2112 or the groove wall through the connecting layer 300 after being inserted into the connecting groove 211. In other words, in the embodiment, the sealingly connected surface between the first side plate 120 and the bottom plate 210 can be arranged horizontally or vertically. Correspondingly, when the area of the sealingly connected surface needs to be increased, the area of the groove bottom 2112 can be increased while the thickness of the first side plate 120 is increased, or the depth of the connecting groove 211 can be increased to increase the area of the groove wall. Moreover, when the depth of the connecting groove 211 is increased, only the thickness of the bottom plate 210 is increased, and the overall width of the battery pack case in the Y direction (e.g. the Y direction of the X-Y-Z coordinate system shown in FIG. 1) is not increased, which provides a structural basis for reducing the overall width of the battery pack. Figure 1 Figure 2

[0043] ​​The battery pack box provided by the application has the following advantages. The connecting groove 211 is arranged on the wall surface of the bottom plate 210, and the connecting layer 300 is arranged in the connecting groove 211. The first side plate 120 extending into the connecting groove 211 can be sealed and connected with the inner surface of the connecting groove 211 through the connecting layer 300, thereby realizing the sealed connection between the upper box body 100 and the lower box body 200, and improving the sealing performance of the battery pack box.

[0044] Meanwhile, the inner surface of the connecting groove 211 includes the longitudinally arranged groove wall, and the first side plate 120 can be sealed and connected with the groove wall through the connecting layer 300. Since the sealed connection surface is longitudinally arranged, the width dimension of the battery pack box is not occupied, which provides a structural basis for reducing the width dimension of the battery pack, improves the volume composition rate of the battery pack in the width direction of the battery pack box, and improves the energy density of the battery pack.

[0045] In addition, the part of the first side plate 120 sealed and connected with the bottom plate 210 is located in the connecting groove 211 of the bottom plate 210, and the bottom plate 210 can provide the first side plate 120 in the connecting groove 211 with covering protection, so that the first side plate 120 is prevented from being deformed due to external impact, and the sealed connection between the first side plate 120 and the bottom plate 210 is prevented from being invalid, thereby improving the sealing reliability of the battery pack.

[0046] For example, Figure 2 In some embodiments, the groove wall of the connecting groove 211 close to the center of the bottom plate 210 is defined as the first groove wall 2111, and the first side plate 120 is sealed and connected with the first groove wall 2111 through the connecting layer 300.

[0047] For example, along the extension direction of the first groove wall 2111 (for example, the X direction in the figure), Figure 2 When the edge of the first groove wall 2111 is flush with the edge of the first side plate 120, the first side plate 120 can be positioned through the connecting groove 211. After the first side plate 120 is aligned with the first groove wall 2111 and inserted into the connecting groove 211, the first side plate 120 is located at the preset position along the extension direction of the first groove wall 2111.

[0048] When the inner side plate surface of the first side plate 120 (i.e., the surface of the plate on the same side as the top plate 110) and the connecting layer 300 are arranged between the first groove wall 2111, only the first side plate 120 needs to be extruded from the outer side plate surface of the first side plate 120, so as to force the inner side plate surface of the first side plate 120 to extrude the connecting layer 300 towards the first groove wall 2111, thereby realizing the sealing connection of the first side plate 120 with the first groove wall 2111 through the connecting layer 300. While ensuring that a space with good sealing between the upper box body 100 and the lower box body 200 can be formed, the assembly difficulty of the battery pack box body can be reduced, which helps to improve the assembly efficiency of the battery pack box body and is conducive to mass production.

[0049] As Figure 2 In some embodiments, the connecting layer 300 is arranged between the first side plate 120 and the groove wall of the connecting groove 211, and between the first side plate 120 and the groove bottom 2112 of the connecting groove 211.

[0050] For example, the connecting layer 300 between the first side plate 120 and the groove wall of the connecting groove 211, and the connecting layer 300 between the first side plate 120 and the groove bottom 2112 of the connecting groove 211 are connected to each other, so that the cross section of the connecting layer 300 perpendicular to the extension direction forms a U-shaped structure.

[0051] For example, the connecting layer 300 in the connecting groove 211 is integrally formed.

[0052] In this embodiment, the connecting layer 300 is arranged between the first side plate 120 in the connecting groove 211 and the inner surface of the connecting groove 211 to realize the sealing connection therebetween. On the one hand, it can form a sealing connection surface with a large area between the first side plate 120 and the bottom plate 210, thereby helping to improve the sealing performance of the battery pack box body; on the other hand, when the connecting groove 211 is filled with the connecting layer 300, the connecting layer 300 also helps to position the first side plate 120 in the connecting groove 211, preventing the relative movement between the battery pack box body and the bottom plate 210 due to external impact during transportation and use, thereby causing the sealing connection between the first side plate 120 and the bottom plate 210 to fail.

[0053] As Figure 3 , Figure 3 An exploded schematic view of the battery pack box body is shown, and in some embodiments, the connecting groove 211 is arranged on the first bottom plate wall surface 212 of the bottom plate 210 facing the top plate 110.

[0054] For example, the connecting groove 211 is arranged near the edge of the first bottom plate wall surface 212 and extends along the edge of the first bottom plate wall surface 212. When the battery cell is installed in the battery pack case, the battery cell is installed on the first bottom plate wall surface 212 inside the first side plate 120, and the first bottom plate wall surface 212 outside the first side plate 120 is not provided with the battery cell. Therefore, in order to reduce the overall width of the battery pack case, the size of the first bottom plate wall surface 212 outside the first side plate 120 can be reduced as much as possible, that is, the connecting groove 211 is arranged near the edge of the first bottom plate wall surface 212.

[0055] The connecting groove 211 is arranged on the first bottom plate wall surface 212, that is, the connecting groove 211 is arranged on the upper wall surface of the bottom plate 210. When the upper case 100 is assembled to the lower case 200, the upper case 100 is arranged from top to bottom near the lower case 200, that is, the first side plate 120 is inserted into the connecting groove 211 with the opening upward, which can effectively simplify the assembly process of the battery case. At the same time, since the connecting groove 211 has the opening upward, when the connecting layer 300 is arranged in the connecting groove 211, the connecting layer 300 can be better retained in the connecting groove 211, avoiding the connecting layer 300 from being taken out of the connecting groove 211, which also helps to reduce the assembly difficulty of the battery pack case.

[0056] In some embodiments, as shown in Figure 3 , the lower case 200 includes an end plate 220 connected to the bottom plate 210 and protruding from the first bottom plate wall surface 212; as shown in Figure 4 , Figure 4 A front view schematic diagram of the lower case 200 is shown, and the connecting groove 211 is arranged near the side wall of the end plate 220; as shown in Figure 2 , the first side plate 120 is connected to the side wall of the end plate 220.

[0057] For example, the end plate 220 is connected to the end of the bottom plate 210 along a second direction (for example, the X direction in Figure 3 ), and the thickness direction of the end plate 220 is parallel to the second direction; correspondingly, the connecting groove 211 is arranged on at least one side of the end plate 220 along a first direction (for example, the Y direction in Figure 4 ), and the first direction, the second direction and the height direction of the battery pack case are perpendicular to each other.

[0058] For example, the top plate 110 can be connected to the end plate 220, so that the upper case 100 and the lower case 200 can form a containing space with good sealing performance.

[0059] For example, a second sealing member 500 is arranged between the top plate 110 and the end plate 220 to increase the sealing performance between the top plate 110 and the end plate 220.

[0060] Exemplarily, the top plate 110 and the end plate 220 , as well as the first side plate 120 and the end plate 220 , can be connected by fasteners such as screws to reduce the preparation cost of the battery pack case.

[0061] In order for the upper case 100 and the lower case 200 to enclose a storage space, the first side panel 120 needs to be connected to the sidewalls of the end panel 220. The connection groove 211 is provided near the sidewalls of the end panel 220. When the first side panel 120 is inserted into the connection groove 211, the inner surface of the first side panel 120 is close to the sidewalls of the end panel 220, facilitating the connection between the first side panel 120 and the sidewalls of the end panel 220.

[0062] In some embodiments, as Figure 3 , a first sealing member 400 is provided between the first side plate 120 and the end plate 220; Figure 5 , Figure 5 Shown Figure 4 In the enlarged schematic diagram of part B, the first groove wall 2111 is flush with the side wall of the end plate 220 close to the first bottom plate wall 212 (hereinafter referred to as the root side wall of the end plate 220), and, as shown in FIG. Figure 2 The thickness of the connecting layer 300 (hereinafter referred to as the inner connecting layer) between the first groove wall 2111 and the first side plate 120 is the same as the thickness of the first sealing member 400 .

[0063] For example, the first sealing member 400 may be a sealant or a rubber sealing gasket.

[0064] For example, the first sealing member 400 and the second sealing member 500 may be connected to each other to form a strip structure covering the sidewall of the end plate 220 .

[0065] For example, the first sealing member 400 and the second sealing member 500 may be integrally formed and connected.

[0066] In conjunction with the foregoing, since the first side panel 120 needs to be connected to the sidewall of the end panel 220, it also needs to be connected to the first groove wall 2111. When the first groove wall 2111 is flush with the root sidewall of the end panel 220, the first side panel 120 can be smoothly connected to both the first groove wall 2111 and the root sidewall of the end panel 220, thereby simplifying the structure of the first side panel 120 and reducing the difficulty and cost of manufacturing.

[0067] At the same time, when the thickness of the inner connecting layer is the same as the thickness of the first sealing member 400, the first side plate 120 forms a sealed connection with the first groove wall 2111 through the inner connecting layer, while also ensuring that the first sealing member 400 can play a sealing role, that is, there will be no mutual interference between the inner connecting layer and the first sealing member 400, which helps to further improve the overall sealing performance of the battery pack case.

[0068] In some embodiments, the connecting layer 300 is a glue solidified layer.

[0069] Before the upper case 100 is mounted, glue can be poured or coated into the connecting groove 211. Exemplarily, the glue can fill the connecting groove 211 as much as possible, so as to ensure that after the first side plate 120 is inserted into the connecting groove 211, there is sufficient glue between the first side plate 120 and the inner surface of the connecting groove 211 to fill the gap between them, thereby improving the sealing performance of the battery pack case.

[0070] When the upper case 100 is assembled to the lower case 200, the first side plate 120 is inserted into the glue in the connecting groove 211, at this time, the glue has fluidity and can automatically fill between the first side plate 120 and the inner surface of the connecting groove 211. After the glue solidifies, a connecting layer 300 is formed between the first side plate 120 and the inner surface of the connecting groove 211, and the first side plate 120 can be sealed and connected to the bottom plate 210 through the connecting layer 300.

[0071] As shown in FIG. 1, the connecting groove 211 is provided with a first groove wall 2111 and a second groove wall 2112 opposite to the first groove wall 2111. Figure 2 In some embodiments, at least one end of the connecting groove 211 penetrates the side wall of the bottom plate 210 along the extension direction of the connecting groove 211 (such as the X direction in FIG. 1). Figure 2

[0072] Exemplarily, the groove wall opposite to the first groove wall 2111 of the connecting groove 211 is further provided with a through hole 2113 penetrating the side wall of the bottom plate 210 along the first direction, and the through hole 2113 is close to the opening of the connecting groove 211. The through hole 2113 can be used as a glue overflow opening to control the height of the glue poured into the connecting groove 211. When the height of the glue in the connecting groove 211 exceeds the preset height, the glue can overflow from the through hole 2113.

[0073] When the connecting layer 300 is a structure layer formed by glue solidification, after the first side plate 120 is inserted into the un-solidified glue in the connecting groove 211, the glue can overflow from the connecting groove 211. If the glue overflows from the upper opening of the connecting groove 211, it can enter the accommodation space and affect the electric core installed in the accommodation space.

[0074] In order to avoid the above problems, the end of the connecting groove 211 penetrates the side wall of the bottom plate 210 in the present embodiment, so that the end of the connecting groove 211 can communicate with the outside. When the glue needs to overflow from the connecting groove 211, the glue can overflow from the end of the connecting groove 211 to the outside, so as to reduce or even avoid the glue entering the accommodation space, and also facilitate the cleaning of the overflowed glue.

[0075] ​It should be noted that the glue filled into the connecting groove 211 can be paste-shaped glue, so as to avoid the glue from flowing out of the end of the connecting groove 211 before the first side plate 120 is inserted into the connecting groove 211.

[0076] As shown in Figure 6 , Figure 6 As shown in

[0077] As shown in Figure 6 , the top plate 110 is connected with two first side plates 120 along a first direction, the two first side plates 120 are arranged at intervals and symmetrical relative to the top plate 110. Figure 3 As shown in

[0078] As shown in Figure 7 , Figure 7 As shown in Figure 6 , the two first side plates 120 are respectively inserted into the corresponding connecting grooves 211, so as to realize the connection of the first side plate 120 and the bottom plate 210 through the connecting layer 300. Figure 6 As shown in
